pycharm将代码同步到远程服务器_全局代理「建议收藏」

1. Pycharm设置

2. urllib下载数据配置

from urllib.error import URLError
from urllib.request import ProxyHandler, build_opener
 
 参数是字典，键名是协议类型，健值是代理
proxy_handler = ProxyHandler({ 
   
    'http': "http://127.0.0.1:12333",
    'https': "http://127.0.0.1:12333"
})
# Opener已经设置好代理了
opener = build_opener(proxy_handler)
try:
    response = opener.open('http://httpbin.org/get')
    # 运行结果是一个JSON
    print(response.read().decode('utf-8'))
except URLError as e:
    print(e.reason)

Torch.geometirc dowload.py数据下载实例：

def download_url(url: str, folder: str, log: bool = True):
    r"""Downloads the content of an URL to a specific folder. Args: url (string): The url. folder (string): The folder. log (bool, optional): If :obj:`False`, will not print anything to the console. (default: :obj:`True`) """

    filename = url.rpartition('/')[2]
    filename = filename if filename[0] == '?' else filename.split('?')[0]
    path = osp.join(folder, filename)

    if osp.exists(path):  # pragma: no cover
        if log:
            print(f'Using existing file {filename}', file=sys.stderr)
        return path

    if log:
        print(f'Downloading {url}', file=sys.stderr)

    makedirs(folder)

    context = ssl._create_unverified_context()
    from urllib.request import ProxyHandler, build_opener
    proxy_handler = ProxyHandler({ 
   
        'http': "http://127.0.0.1:12333",
        'https': "http://127.0.0.1:12333"
    })# Opener已经设置好代理了
    opener = build_opener(proxy_handler)
    data = opener.open(url)
    # data = urllib.request.urlopen(url, context=context)

    with open(path, 'wb') as f:
        f.write(data.read())

    return path
